Processed meat products and snacks consumption in ADHD: A case-control study

Area of Science:

• Pediatric Nutrition
• Neurodevelopmental Disorders

Background:

• Attention-deficit hyperactivity disorder (ADHD) is increasingly linked to dietary patterns, yet research on specific food groups like processed meats and snacks remains limited.
• Understanding the relationship between specific food consumption and ADHD symptoms is crucial for developing targeted nutritional interventions.

Purpose of the Study:

• To investigate the association between attention-deficit hyperactivity disorder (ADHD) and the consumption of processed meat products and snacks.
• To explore the correlation between ADHD symptoms and the intake of processed foods in children.

Main Methods:

• A study involving 390 children (ages 6-17) with 169 diagnosed with ADHD and 221 healthy controls.
• Food consumption assessed using a modified food frequency questionnaire focusing on processed meat and snack items.
• ADHD symptoms evaluated using the Turgay DSM-IV-Based Child and Adolescent Disruptive Behavioral Disorders Screening and Rating Scale and Conners' Rating Scale.

Main Results:

• Children with ADHD exhibited higher consumption of processed meat products, milk-based desserts, and chocolate-sweets compared to controls.
• A significant positive correlation was found between ADHD symptom severity and the intake of various snacks, including chocolate-sweets, sujuk, chocolate, jelly beans, sweets, cakes, and chocolate spread.
• ADHD symptom scores correlated positively with overall snack consumption.

Conclusions:

• Children diagnosed with ADHD tend to consume greater quantities of foods high in saturated fat and sugar.
• The consumption of processed foods by children with ADHD may be associated with the manifestation and severity of ADHD symptoms.
